Open File In Directory With Part Of Filename As String

I have a Workbook "forecast.xlsx" and several Workbooks which have a individual Number in the Filename (E.g. "3960........xls", "3961.......xls etc.) in the same directory as "forecast.xlsx" + projects"

Now, I would like to browse through "forecast.xlsx" in column H, searching for hyperlinks. In Column H are these Projectnumbers located which are used in the filenames above. Whenever the Cell cointains a hyperlink, following should happen (that far i managed it by myself):

- Store the Cellvalue in a String Variable
- Go to the Directory this.workbook + projects
- browse this folder, searching for a File which contains the stored string in its filename
- open the file
- copy a range
- close file
- This.workbook.Activate
- follow the Hyperlink which has been stored as String before
- paste selection
- continue browsing through column H, looking for the next hyperlink.

I have a VBA which runs bugless, but it copies the wrong range, but to the correct destination.

See the code below:

Sub RESLT_INPUT_ALL()
Dim cell As Object
For Counter = 1 To 1000
Set cell = Worksheets("Projects overview").Cells(Counter, 8)
If cell.Hyperlinks.Count > 0 Then
